Product news

We have successfully developed and released a high-efficiency Short-Wavelength-Infrared (hereinafter SWIR) LED chip series which has the world’s highest efficiency in the peak wavelength range of 1,200 to 1,900 nm.

The newly developed SWIR-LED chip has higher luminous efficiency, achieving 170mW output power with a 1mm square chip at 1,350nm, two times higher than comparable products. Even at 1,900nm, where it is considered difficult to improve luminous efficiency, the 1mm square chip achieves 45mW, 30% more power compared to the conventional devices. Such significant power increase improves analysis and testing accuracy, and reduces power consumption.

In addition to the 350 µm square and 1 mm square chip sizes, DOWA is introducing a 250 µm square version to its SWIR-LED series.
When paired with a DOWA InGaAs Photo Diode already in mass production, the new SWIR LED can be used in sensors. Being offered in 3 different sizes, DOWA SWIR LED can be used in a wide range of applications from telecommunication equipment and wearables that require device miniaturization to machine vision where high radiant power must be required. The DOWA SWIR LED is expected to expand its market and sales.
